Thanks for creating the separate thread. I'll try and take a look at the source code of rich:fileUpload today and see if we can make it work it in the bridge. I'll let you know some more info as soon as I know more.

Just wanted to let you know that I've done a high level review of the code. Facing similar challenges to those found in the PrimeFaces code. We'll see what we can do. Again, I'll post an update when I know more.

You're very welcome. I got rich:fileUpload working in the bridge and updated the richfaces4-portlet demo accordingly. You will need to download the 3.0.0-RC1-SNAPSHOT (Liferay 6.0.x) or 3.1.0-RC1-SNAPSHOT (Liferay 6.1.x) version of the bridge or the richfaces4-portlet demo to try it out.
